Great Views and a Great Lake
The Deep Lake area of Flat tops Wilderness offers a variety of scenic hikes and drives as well as 4x4 trails and great lake fishing. The drive up to this area is up a dirt road about 10 miles, the road can be a beat beat up in areas. I blew a tire on my truck on the way up. Other than that the drive up is very scenic, you will pass the deep creek overlook and can see Aspen, Beaver Creek, and Vail Ski Resorts all in the same view.
The campgrounds are very large and spaced out. We went with a large group, 5 cars and many tents and had plenty of room. Some site are able to accommodate an RV or trailers. Sites vary between open and exposed to set against the forest for shaded. Restrooms were located fairly close to our spot and i remember it being one of the cleanest vault toilets i have ever used! Each spot also has a metal fire pit with a grill over top.
Like i mentioned earlier the Deep Lake area is a great base camp to go out and explore. You will find many people driving off road vehicles around. The fishing in the lake is also very good, the Forest Service stocks the lake every year. Lastly the campground sits at 10.500 ft so it does gets chilly up there even in the middle of summer.
